Verfahren zum Nieten eines Kontaktstückes auf eine Platte aus thermoplastischem MaterialMethod for riveting a contact piece onto a plate made of thermoplastic material

Die Erfindung "betrifft ein Verfahren zum Befestigen von Kontaktstücken auf einer Grundplatte aus thermoplastischen Material, insbesondere zur Herstellung von Verbindungskasten von Telefonapparaten.The invention "relates to a method of fastening of contact pieces on a thermoplastic base plate Material, in particular for the manufacture of junction boxes for telephone sets.

Bei den bekannten Geräten dieser Art sind die Kontakt stücke im allgemeinen an der Grundplatte mit Hilfe von Schrauben, Nieten oder Ösen oder durch gebogene Laschen befestigt unter Verwendung von Öffnungen in der Grundplatte. Dies kennzeichnet einen Nachteil, insbesondere für Kästen zur Wandbefestigung, da im Fall von Feuchtigkeit in der Wand, an der der Kasten befestigt ist, die Verbindungen nicht gegen diese Feuchtigkeit geschützt sind.In the known devices of this type, the contact pieces are generally on the base plate with the help of Screws, rivets or eyelets or fastened by curved tabs using openings in the base plate. This characterizes a disadvantage, especially for boxes for wall mounting, since in the case of moisture in the Wall to which the box is attached, the connections are not protected against this moisture.

Die Erfindung vermeidet diesen Nachteil und gibt einen einfachen und wirtschaftlichen Weg an zur Befestigung der Kontaktstücke an einer Platte aus thermoplastischemThe invention avoids this disadvantage and provides a simple and economical way of fastening the contact pieces on a plate made of thermoplastic

Die Erfindung ist dadurch gekennzeichnet, daß die Platte mit Vorsprüngen versehen ist, die als Nieten verwendet werden können, daß Nietlöcher in den Kontaktstücken vorgesehen sind, wobei die Innenseite der Löcher mit Nuten versehen ist, z.B. einem Gewinde, und daß das Treiben eines Niets nach dem Aufbringen eines Eontakt st lickes mit Hilfe eines Domes vorgenommen wird, welcher mit Ultraschallfrequenz vibriert.The invention is characterized in that the plate is provided with projections which are used as rivets can be that rivet holes are provided in the contact pieces, the inside of the holes with grooves is provided, e.g. a thread, and that driving a rivet after applying a contact st lickes with the help a dome is made, which vibrates at an ultrasonic frequency.

Die Erfindung wird weiter mit Hilfe einer Ausführungsform unter Bezugnahme auf die beiliegende Zeichnung beschrieben, in der dieThe invention will be further elaborated with the aid of an embodiment with reference to the accompanying drawing described in which the

Die Löcher, die alle gleich sind, werden durch ein "Flanschen" erzielt und danach mit Gewinde versehen. Zum Tragen des Kontaktstückes ist eine Basis 3 auf einer PlatteThe holes, which are all the same, are made by "flanging" and then tapped. To the Supporting the contact piece is a base 3 on a plate

2 angeordnet, wobei die Basis mit Aussparungen versehen ist, um die Löcherflansche 9 des Kontaktstückes aufzunehmen. Die Mittelaussparung 4 ist kreisförmig und besitzt in ihrer Mitte einen Vorsprung 5, der als Niet benutzt werden kann. Das Kontaktstück wird aufgesetzt (Figo 5), und mit Hilfe eines mit Ultraschallfrequenz vibrierenden Dornes 6 wird der Niet eingetrieben (Fig. 6). Beim Bin- Λ treiben des Niets unter Vibration wird dieser erwärmt, so daß die Oberflächenschichten des Kiets erweicht werden. Im konischen Abschnitt 7 nahe dem Dorn sowie im anderen konischen Abschnitt 8 am Unterteil des Nietes bleibt die Temperatur jedoch verhältnismäßig niedrig aufgrund der Berührung mit dem Dorn bzw. der Verbindung mit der Grundplatte, so daß diese Abschnitte sich nicht erweichen. Beim Herabdrücken des Dornes werden die konischen Teile aufeinander zugedrückt, wodurch die weichen Abschnitte des Niets radial nach außen gedrängt werden, um das Gewinde des Loches auszufüllen. Die Endform des Nietes wird in Fig. gezeigt. Durch die Flansche 9 der Schraublocher, die in den rechteckigen Aussparungen 10 liegen, wird eine Drehbewegung des Kontaktstückes beim Befestigen der Schraube vermieden, und es wird auch verhindert, daß der Niet einer zu großen Torsionskraft ausgesetzt wird.2 arranged, wherein the base is provided with recesses to receive the hole flanges 9 of the contact piece. The central recess 4 is circular and has in its center a projection 5 which can be used as a rivet. The contact piece is put on (FIG. 5), and the rivet is driven in with the aid of a mandrel 6 vibrating at an ultrasonic frequency (FIG. 6). When bond Λ of the rivet drive under vibration the latter is heated so that the surface layers of Kiets be softened. In the conical section 7 near the mandrel and in the other conical section 8 on the lower part of the rivet, however, the temperature remains relatively low due to the contact with the mandrel or the connection with the base plate, so that these sections do not soften. When the mandrel is pressed down, the conical parts are pressed towards one another, as a result of which the soft portions of the rivet are urged radially outwards in order to fill the thread of the hole. The final shape of the rivet is shown in FIG. The flanges 9 of the screw holes, which are located in the rectangular recesses 10, prevent a rotational movement of the contact piece when the screw is fastened, and it is also prevented that the rivet is subjected to an excessive torsional force.

Beim Befestigen des KontaktStückes auf diese Weise bestent keine Notwendigkeit für Öffnungen in der Grundplat-When attaching the contact piece in this way no need for openings in the base

Das Verfahren ist besonders geeignet für automatische Herstellvorgänge. Wenn eine Anzahl von Eontaktstücken gleichzeitig auf jeder Grundplatte angeordnet werden soll, wird für jedes Eontaktstück ein Dorn vorgesehen, so daß alle Nieten in einem Arbeitsgang eingetrieben werden.The method is particularly suitable for automatic Manufacturing processes. When a number of contact pieces are arranged on each base plate at the same time is to be, a mandrel is provided for each contact piece so that all rivets are driven in in one operation will.
